Evidence for olfactory search in wandering albatross, Diomedea exulans

Evidence for long-range olfactory detection. Sample track illustrating upwind flight after a series of sit-and-wait feeding events. The bird took off and meandered upwind for ≈20 km before touching down again to feed repeatedly on the water at a hotspot. Open circles indicate feeding events. Arrows refer to flight and wind direction as indicated. Note that wind direction shifted by ≈5° over the course of the bird's flight. The horizontal and vertical distances represented by the smallest grid rectangle are shown in the lower right corner.
